Great speakers if you don't have the room for the 6501s!

Review written by johan from Redondo Beach, CA

The MM5251s are awesome speakers, but the slightly larger MM6501s have a much lower frequency response and therefore sound much better.

If you don't have the space, or if you have a sub, then it does not matter!

I know because I have both sets in two different cars.

I highly recommend all Polk MM series speakers for their build quality, design, and warm clear sound.

Review written by Mike from Phoenix, AZ

I have read other speaker reviews when the writer would speak to "hearing notes and instruments I had not heard before..." Now I know what they're talking about. I haven't even installed my sound processor or amp and my OEM stereo sounds great.
